Rosalie Peak

Route: Rosalie Group

Info: Snow free up to saddle, a couple remaining snowfields between 13,200 and summit. Can connect the dots to avoid most of them if you really try. Trail runners were just fine.

Info: Solid bootpack from the TH to about 2.75 miles in the middle of the switchbacks. I broke trail up to the ridge. I got lost in the woods a few times and sank to my knees despite the snowshoes where I lost the trail. There was some whumpfing in the snowpack just after breaking treeline on ascent and descent. With the whole route on low-angled slopes and not underneath anything steeper I carried on - but a warning to those traversing steeper slopes in the area. I left my snowshoes at the saddle as the ridge was mostly dry and didn't bother with crampons for the snowy patches. Beautiful, warm February day.

Info: Full summer conditions, no snow or anything. Still in great shape up high, cruiser trail down low! Some solid fall colors too

Info: Other than some mud in the willow crossing at treeline, the whole route is doable without getting your boots wet. Leaves starting to change; some nice displays along the Tanglewood Trail and visible from the summit. Great time of year to invest in some bright orange gear if you are lacking any - I saw one hunter coming back to his truck yesterday as I was pulling into the TH. Only saw hikers on the trail and ridge, but safety consciousness is always a good idea.

Info: Alternate, shorter and enjoyable route for doing these three...does require a Mount Blue Sky Reservation. Full report: https://www.coloradomountainpack.com/post/epaulet-mountain-epaulie-rosalie-peak

Info: The trail is in great condition. Only one snow field to go through. Its maybe 100 yards or so. But overall, its mostly just wet.

Info: Starting at the Deer Creek TH, we skinned up the Tanglewood Trail using a nice trench to treeline. From there we gained the ridge and left our skis a little below the summit. We booted the rest and then returned to ski out. Snow was good below treeline, but pretty poor above. We did find some stashes of decent snow, but most of it was blown off from heavy winds.

Info: Climbed Rosalie Peak today from Deer Creek Campground; we parked anywhere from 0.25-0.5 after the campground. At the beginning, there is some boot pack that tapers off. Snow was pretty deep in treeline, and we put in a snowshoe trench around the switchback area. Around 12,000ft the conditions are variable - we encountered everything from major postholing, bulletproof snow, and tundra. We were the only ones who went to the summit today.

Info: The Road form Summit Late to Mt Blue Sky seems to be totally snow free. From the road to Epaulet and Rosalie there was an inch of snow over a good portion of the ground but it was a non issue.

Info: consistent 4-6 inches on the final ascent on Saturday. Seems like it might have melted by now!! Full report here: https://www.coloradomountainpack.com/post/rosalie-peak

Info: Nearly summer conditions. 50' of consolidated snow right below the saddle with a good boot pack. Some snow near the summit, all avoidable. Traction not needed nor helpful. Continued to Epaulie and Epaulet; notes on those peaks' pages. On the return, feasible to skirt about 100' below Rosalie's summit on the east, but not more. Handful of folks on the trail to and from Roosevelt Lakes in the morning and afternoon; after leaving the saddle, had the mountains to myself until descending and saw 5 people and 2 dogs ascending Rosalie. FWIW, my GPS marked this route at 15.4 miles and 5400'.

Info: Multiple sections of the trail below treeline are a creek, but it is rarely too deep. If it is there are always rocks to hop on - I wore trail runners and never got wet. Two 30' patches of snow are on the trail prior to the saddle but didnt require any traction. 4-5 unavoidable snowfields above 13k didnt require traction either, but they do have about 6' of ice below each of them due to daily melt - plenty of rocks are poking through that made it easy to navigate. Head on wind was brutal and prevented me from wanting to finish the group.

Info: Completely Clear to Treeline, some short snowfields but nothing that was long or steep enough to require traction. Was incredibly windy yesterday but there is a good wind break built up top and also one close to 13200 ft. Bring layers and warm gloves.

Info: Trail was in great shape. Some snow fields mostly when you get out of treeline. I brought spikes and didn't need them, flotation definitely not necessary.

Info: There are a couple really small patches of snow/ice the first 1.2 miles to the wilderness boundary. From miles 1.2 - 1.8 the snow/ice is consistently intermittent. Once beyond mile 1.8 it is consistent snow until the open spaces near treeline. Snow was fairly consistent to the saddle. From the saddle to the summit it was 80% tundra with most of the snow being the last few hundred feet to the summit. After a freeze the trail is hardpacked and easy to follow. Once it warms, buyer beware. I descended a little before noon and it was postholeapalooza from the saddle down to the trees. Once in the trees the shade helped at least maintain some of the firmness. I didn't use traction or flotation. I don't think flotation would have helped.
